Have you ever seen a car on the street and don't know what brand and model is that? Just use MudCar to take a photo of that and it can tell you immediately. Not only can it distinguish different brands, but also models of different model years, from classic cars in the 60s to newly-released 2025 models. MudCar is backed by a deep learning neural network. Rather than relying on existing image datasets and others' APIs, we build our image datasets, and train the model on our own.
NerdTrack

NerdTrack records your location in a CSV file on your phone. No other data is collected and no data ever leaves your device. Full source is available at https://nerdtrack.org There is no interactive UI. Just grant location permissions, and it will log in the background. To stop logging, remove location permissions or uninstall app. The app uses the SignificantLocation and CLVisit APIs. The accuracy is low but it has very low battery usage. To get your log, open the Files app, and look for locations.csv in the Nerd Track folder. A config file will be created in the app's documents folder the first time it runs. Edit that file to change logging frequency or minimal distance. Force-stop and restart app to reload config. By default, the app records location: - Every 15 minutes, if you have moved more than 300 meters The CSV logs timestamps in the unix epoch format. Use 'dateconv -i %s' to convert it to something more human-readable. Some helper scripts are available at https://nerdtrack.org

Verdict
The clearest difference is ads: NerdTrack at none against MudCar's shown. MudCar's advantage is update cadence (weekly vs every 2 months) and iOS requirement (16.6 vs 18.0). On price, in-app purchases and device support there is nothing between them.
